Be it known that I, SAMUEL WALKER, e citizen of the United States, residing et Jerome, in the county of Yevepei and Stat-e of .frizonn have invented new and useful Improvements in W heeled Scrapers, of which the following is e specification.

This invention. relates to n Wheeled scraper.

The principal object of this invention is to provide n scraper for gathering and. carrying soil, seid scraper being provided with Wheels which 'allow thevshovel to he raised and carried over the ground without' dragging.

Another object of this invention is to provide a scraper of the above class V.vliicliis tted with adjustments so that the scrap ing shovel may be canted to any desired angle, and may he raised, lowered and dumped, when desired, by an operator riding` upon the implement.

Other objects will appenrhereinziiter.

The invention is illustrated., by way of exoiniole. in the accompanying drawings in completely assembled scraper, particularly showing the dispos.' tion oit the scraper shovel in relation to the running" ,g1g/enr und, frame the vehicle. f

engaged by e. lever 37. A ceble 8 8 fastened it, seid cable extending Patented June itil, todo. se-nai no. weer-sc.

secured to shovel brackets 21 by. pins 22.

rlhese brackets are fastened upon the rear well of a. scraping shovel 23. As particu larly shown in Fig. l, the scraping shovel is of considerable width and extends outwardly :it opposite sides of the frame and the running gear, it having side boards and forward scraping blade. This shovel is held in its norninl upright position by trip dogs 2li which ere pivoted to the downwardly extending portions of the frame and overhnng and the ripper edge of the shovel rear woll. to hold the shovel in en upright position and when raised will release it to dump 'the material. therefrom, thus allowing the shovel to assume the dotted .line position indicated in Fig. 2.

The shovel may he raised and lowered 'at its front or rear ends, either simultaneousiy or seperately. This is accomplished by .the

'lifting lever E25 which is pivoted upon the freine and has o downen" adapted to c nnect with This chain is secured :it y to the frame elements 1'? and ver 25 is adopted to be swung if; when it hes been actuated *o ends of the freine members .may be secured by e catch Early shown in Fig. l...

The e end of this cable is connected to en epe .iting lever 35 which is preferably inoin'xted along the rightdnind side of the freine l2 and when shifted will conse the shaft 30 to rotate in a forward or reverse directionu A ratchet plete is These dogs will not` rovided to be eiign'ed b the lever s'tlmt l t) it may be locked :it any desired point in its travel. The opposite side of the ratchet plate is :fitted with teeth edapted'to he This lever-has e.

forwardly end l:n.onnd s. pulley 39.- The imi hill@ may be rotated and the shovel tially horizontal y device here disclosed, soil 'and graded, as desired, and

an axle mounted of the shovel and at the center thereof. By ymanipulation of the lever 37, the shaft 40 drawn up from its dotted line position to the full line position as shown in Fig. 2.

In operation, the shovel normally drags upon the ground, due to the fact that the lifting lever 25 is raised and the lever 35 is swung forwardly to unwind the cable 29. It will be understood that the locking pawls 24 are normally in engagementJ with the back of the shovel as shown in Fig. 2, tius holding the floor of the shovel in a substanposition. after the shovel has been filled with'dirt, the lift-ing lever may be swung down and locked, as shown in Fig'. 2, and the lever 35 swung rearwardly to wind the cable 29. This will elevate the shovel. When it is desired to release the shovel to dump the dirt therefrom, the operator, seated upon the seat 42, depresses a foot pedal 43 to draw catch cables 44 and 45 rearwardly. These cables pass around idler pulleys 46 and 47 upon the frame, and thereafter over pulley wheels 48 and 49 rotatably mounted upon a shaft 50. The ends of the cables then are connected separately to the dogs 24. It has been found convenient to utilize the shaft 50 as a pivotal mounting for the lifting lever 25. `When these pawls are lifted, the scraper shovel will fall. The shovel may be restored to its normal position by drawing the lever 37 rearwardly and thus rotating the shaft 40 to wind the cable 41 and lift the forward end of the shovel.

llt will thus be seen that by the use of the may be scraped the bucket may be filled and carriedy to any point without dragging'.

While I have shown the preferred construction of my Wheeled Scrapers as now known to me, it will be understood that various changes in the combination, construction and arrangement of parts may be made4 by those skilled in theart without departing from the spirit aof my invention.

ll claim:

1. In a wheeled scraper, a rectangulai` main frame, brackets extendingdownwardly from the frame at the front Iland rear ends,

in the rear brackets,a kingpost mounted in the front bracket, an axle connected to the king-post, Wheels upon the axles, a knuckle` pivotally and slidably mounted upon the king-post, a sub-frame pivotally connected to the knuckle and eX- tending 'horizontally backwardly beneath.`

the main frame; said sub-frame consisting of oppositely diverging bars turned downwardly at their rear ends; shovel brackets pivotally connected to the rear lower ends,

a scraping shovel fastened to the shovel ing the shovel to operative position 'after it has been dumped, and means for raising and lowering the sub-frame to raise and lower the shovel.

2. In a Wheeled scraper, a main frame, a king-post vertically mounted and extending downwardly from the main frame, a knuckle slidingly and pivotally mounted upon the kingpost, a sub-`frame comprising diverging bars having down turned rear ends; the forward ends being pivotally connected to the knuckle; shovel brackets pivotally connected to the down turned rear ends, a shovel connected to the shovel brackets, trip dogs for holding the shovel upright, means for operating the trip dogs to dump the shovel, means for returning the shovel to its normal position, .a lifting lever pivotally mounted upon the main frame, a chain connectini); the lifting lever to the rear end of the sub-fra1ne; so that by operating the lifting lever the rear end of the sub-frame may be raised or lowered; a shaft mounted at the forward end of the main frame, a cable wound upon the shaft and attached to the forward end of the sub-frame, a pulledv upon the shaft, a -cable operating pulley, and an operatingr lever mounted upon the main frame and connected to the cable; so that by manipulating the operating lever the forward end of the sub-frame may be raised or lowered.

.ln testimony whereof l have sinned my name to this specification.
